SCHEMTRAC PARTICLE COUNTER SENSOR The PC3 Particle Counter Sensor is an essential tool for municipal and industrial water treatment applications including filter performance monitoring, protecting RO membranes from colloidal fouling, and virtually any application where there is a concern of potential contamination in a clean liquid. The PC3 offers an excellent addition or alternative to other traditional measurements like turbidity (NTU) and Silt Density Index (SDI) testing. Particle counters are best known for their ability to detect when a filter has reached the end of its run well ahead of any impact to NTU readings. The more compact PC3 Particle Counter brings all the great features of Chemtrac's PC3400 model to the HydroACT family of analyzers. Customers can connect multiple sensors to the HydroACT analyzer, or mix and match the PC3 with other measurements like pH, chlorine, and UV254 for organics monitoring. The PC3 allows the user to view up to 3 channels of data in multiple measurement formats including “Total ppb”, “Total Counts”, and counts or ppb in individual size channels (e.g. 2 to 5 micron, 5 to 10 micron, etc.). Full integration between the sensor and analyzer means all sensor settings, including user-friendly calibration features, can be accessed from the HydroACT's user interface. Contact Chemtrac to discuss your application and let us find the right solution for you.
